Application filed January 3, 1921. Serial No. 434,502.

T0 all whom t may concern.'

'Be it known that l, CORNELL FLAGSTAD, a citizen of the United States. residing at Minneapolis, in the county of Hennepin and State of Minnesota` have invented a new and useful Box Cover and Fastening for Same, of which the following is a specification.

My invention relates to boxcovers and fastening means for same. The main object is to provide a box or crate with an improved cover and means for holding the cover engaged with the box both when the box is set up and when it is folded in case it is a foldable box. i

ln the accompanying drawing: Fig. 1 is a top view of a box or a crate equipped with my improved cover and fastening. Fig. 2 is an enlarged section on the line 2-2 in Fig. 1, showing the box, however, as a foldingbox set up and also in dotted lines as folded. Fig. 3 is a top view of Fig. 1, or any other box having my cover and cover fastening means, in a certain modified form. Fig. i is an edge view of the cover and its fasten ing means in Fig. 3. Fig. 5 is a top view of the cover and fastening means further modified. Fig. 6 is of Fig. 5. Fig. 7 is an edge view of Fig. 5. Fig. 8 is a top view of the box with the cover and fastening means further modified. Fig. 9 is a partly sectional edge view of the cover and its fastening means in Fig. 8. Fig. 10 is a vertical section through a portion of the box and its cover showing in detail one form of the fastening means. Fig. 11 is a face view of the plate SO in Fig. 10. 12 is another view like Fig. 10, but showing somemodification in the box and fastening means for the cover. Fig. 13 is a top view of the socket 32 in Fig. 12. Fig. 14Cl is a face view of Fig. 13. Fig. 15 is a modi-A fication of Fig. 14. Fig. 16 is a face view of a hook-shaped'substitute for either Figs. 11, 14k or 15. Fig. 17 shows the device in Fig. 16 applied to the box and its cover.

Referring to the drawing by reference numerals, 2O designates a hollow base in which side members 21, 22 and end members a right hand end view 23, 24 of the lbox are hinged at 2Oa and other points (not shown), so as to fold upon each other, upon the bottom of the base as indicated in dotted line in Fig. 2, when the box is of the kind folding into a hollow base;

but, as already stated, my invention is ap-I licable also to unfoldable boxes.

In all the views where the box cover is shown it is designated by the numeral 25, and is preferably composed of several boards secured with their ends upon two parallel cleats 261 and an intermediate cleat 27, except in Fig. 3 where cleat 27 is omitted and a board 28 is secured with its ends to the underside of the right hand ends of the cleats 26, for a purpose presently to be de-v scribed.

In all the forms shown one edge or end of the cover is provided with rigid fingers 29 adapted to be inserted in suitable catches fixed on the adjacent upstanding member of the box; said fingers 29 as well as the fingers 29a at the opposite end or edge of the cover may preferably be hook-shaped as at 29h, but for small boxes they may be plain, as to the left in Fig. 9, and they may be of either metal or wood. rllhe catch or socket in which said fingers engage each be either a plain plate as 30 in Figs. 10 and 11 with a hole 81 in it, or a socket as 32 with hole 33 in it, or a plain bracket like 32a in 15,

though bulged forward at the middle the same as 32 in Fig. 13. Gr, the catch on the box may be a mere hook, like 34 in Figs. 16 and 17. rrFhe form of catch 32 or 32a is preferable in cases like Fig. 12, in which the wall 24; of the box has its upper portion offset outward by being formed as a reinforcing cleat 24a. and the cover 25 or its' cleats 26 rests upon the top of the portion 24 of the wall, the catch 32 serving to reach across a space which is created by making the cover so small that it will, when the box is folded pass down between similar catches 32X (see Fig. 2) in the vertical part of the base and engage them with the same fingers 29 and 29a.

ln all the forms shown practically the entire cover is rigid and thereby very stiff and strong. ,Only at one end or edge of it the fingers or locking members are in some way l sealing wire or for the bail 'ot a padlock placed as 40 in Fig. l, when the cover isto be secured for a longer time. When the cover is to bev put in place the iingers` 29are first inserted while the cover is at an incline, the board 35 is then tilted as in dotted line 35 in Fig. 2, while the lingers 29n are`inserted; the cover and the board; 35 are then vbrought down to horizontal position and either a cotter pin (not shown) or a sealing wire or thepadlocli applied. Toiopen and remove the. cover requires-simply a reverse operation to that just described.l

ln Figs. 3 and 4, where the board is shown as open and resting in idle position upon the cover, said board is hinged at` 4l to the adjacent board 25x-oir' the cover and the post 38 is lixedkin a secondftolding board42, oil

ity may project through said boardfrom.

board 28. rlhe board 42 carries the inger29a and bein-g hinged at.43 upon the cross board 28 it may told flat down upon the latter between the cleats 26. This being done the board 35 is I'folded upon board 42fand se:-

cured to post 38 the same as described about Figs. l and 2. In the cheapest construction pegs 43X or other'obstructions against the edge of board 42 take the place` ot the hinges 43.

ln Figs. 5, 6 and 7 each linger or catch member 29a is an independent beam-lever hinged near its middle, as at 26X, to one of the cleats 26,1 upon which one. arm-of thet lever'is held down by a boai'd'ai, hingedat 36', the same as in Figs. l and 2,'wlien the outer arm or finger 29 of the lever is inthe catch member on the box, and theboard 35 is then folded down and:secured as in F ig.

' l, only that it folds in the opposite direction.

ln Figs.` 8 aiid9 the yfingers 2921 are securedlacross the underside of a board 35, which 'is hinged at 43'to the cleats 26 vand is lield down flat upon cleats 26,` 27 by the board 42a,which isrhinged atl 4l and arranged'to' fold'iupon the cleats between lthe boards and-25x and thus restv upon the projectingportions 2Q ot the` members 29a. The'ipostSS-'and hole 39 are the saineas in Figs. lj and ln kF ifi wsigiiates a' j iivoted heel; adapted to be en th.' peatlf asl-Ia tcmjjiorary locking means.-

The main advantages ot the invention are @ed in the aperture of" that the fingers on the cover are tiltable and hoo-k shaped so that they may be engaged as hooks and thus resist spreading or bulging oit the walls ot the box when the latter is packed with goods lnthis connection it will be understood that the hook fingers may be increased in numbers according to the size of the box; andithat their shape may be considerably altered Without diverging from the spirit and scope of the invention, themain-` features of which rej side i l j j, the construction of the cover.
